BACKGROUND OF THE INVENTION Technical Field

The present disclosure is directed to virtual outfit fitting technologies, and in particular to systems and methods for virtual outfit fitting based on a smart wardrobe.

Description of Related Art

The “background” description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description which may not otherwise qualify as prior art at the time of filing, are neither expressly or impliedly admitted as prior art against the present invention.

Conventional methods of shopping involved customers visiting physical stores to select and try on outfits before making a purchase. Customers prefer physically trying on the outfits to ensure the outfit is of correct size, the outfit properly fits and match their body figures, the outfit is comfortable and the like. Also, sizes for a customer often differ from one brand of clothing to another and from one style to another. So, the customers prefer to physically wear and test the outfits before making a purchase decision. However, physically wearing and testing the outfits is a time consuming process as a customer has to wear and test several outfits before the customer can decide on design, color, size, fitting, etc., of an outfit that satisfies him or her. In some situations, the customer may have to wait in a long queue outside a fitting room in order to wear and test the outfit. Many times the customers get frustrated due to long waits and may not make a purchase. Also, sometimes the customers worry about hygiene issues. Especially during a pandemic customers are reluctant to wear the clothing for testing.

Online shopping provides respite and an alternative to physical shopping. In online shopping, customers make a purchase and size selection decision based on two dimensional (2D) images of the outfits and choosing sizes which they deem accurate. With the problem of non-standard sizing of clothes by different brands, the chosen size may not be accurate. These methods are not accurate and not interactive in providing the right sizes and choices to the customers. As a result, many times customers end up buying wrong sizes and return the product soon after. This results in loss of sales, loss of trust in brands, loss for brands in shipping and return costs and wastage of merchandise.

A system for generating an image of a first user in a garment was described in U.S. Pat. No. 10,134,083 B2 “Computer implemented methods and systems for generating virtual body models for garment fit visualisation” and a computing device for controlling a movement training environment was described in U.S. Pat. No. 10,134,296 B2 “Enhancing movement training with an augmented reality mirror”, each of which is incorporated herein by reference in its entirety. However, the systems described in these references and other conventional systems suffer from various limitations. The lack of sizing standards combined with unreliable labeling cause outfit fitting problems, which in turn cause a very high rate of outfit returns, lost sales, time wasted in fitting rooms, and a bad shopping experience.

Aspects of the present disclosure are directed to a system for facilitating virtual outfit fitting. The present disclosure allows users to select and try different outfits without physically wearing them.

FIG. 1 depicts architecture of a system 100 including a smart closet device for facilitating virtual outfit fitting, according to exemplary aspects of the present disclosure.

According to aspects of the present disclosure, the system 100 includes a smart closet device 102. The smart closet device 102 provides visuals of users wearing different outfits without actually wearing the outfits. In other words, the smart closet device 102 is designed to help the users visualize how the outfits will look on them, without having to physically wear the outfits. By providing such visuals, the smart closet device 102 assists the users to make purchase decisions or at least help the users to narrow down the selection to a few outfits before physically trying them on in a retail setting. In a home setting, the smart closet device 102 assists the users in deciding which outfits to wear. Examples of an outfit include, but are not limited to, a shirt, a t-shirt, a top, a dress, a sweater, a sweatshirt, a skirt, a trouser, and a jacket. According to aspects of the present disclosure, the smart closet device 102 may be deployed in retail stores, home closets, or any other appropriate places to facilitate the process of selecting and trying on outfits without physically wearing them. The description hereinafter is explained with reference to outfits (or clothes) only for the purpose of explanation, it should not be construed as a limitation, and it is well appreciated that the present disclosure may also be applicable to various articles such as shoes, eyewear, fashion accessories, and the like.

In some aspects of the present disclosure, the smart closet device 102 may be of a rectangular prism shape. A rectangular prism is a polyhedron whose surface is formed by two equal and parallel rectangles called bases and by four lateral faces that are also parallel rectangles and that are equal to their respective opposing faces. Although the smart closet device 102 is described to be of the rectangular prism shape, in other aspects of the present disclosure, the smart closet device 102 may be designed in any desired shape and size. In accordance with the present disclosure, for the purpose of facilitating virtual outfit fitting (i.e., facilitating the process of selecting and trying on outfits), the smart closet device 102 of the present disclosure may be initially trained over a plurality of outfits. Smart closet device 102 may store a machine learning algorithm in memory 106 that is trained to predict or recommend outfits based on determining a user within a vicinity of image sensors 112. In an aspect of the present disclosure, the process of selecting and trying on the outfits by the users is performed in real-time. In some aspects of the present disclosure, the smart closet device 102 may be pre-trained or may be trained in real-time. In some aspects of the present disclosure, the smart closet device 102 may be trained when the smart closet device 102 is idle i.e., not in use. In an example, the smart closet device 102 may be trained as and when new outfits arrive at the retail store in which the smart closet device 102 is deployed.

An initial overview of machine learning and prediction is first provided immediately below and then specific exemplary embodiments of systems, methods, and devices for facilitating virtual outfit fitting are described in further detail. The initial overview is intended to aid in understanding some of the technology relevant to the systems, methods, and devices disclosed herein, but it is not intended to limit the scope of the claimed subject matter.

In the world of machine prediction, there are two subfields knowledge-based systems and machine-learning systems. Knowledge-based approaches rely on the creation of a heuristic or rule-base which is then systematically applied to a particular problem or dataset. Knowledge based systems make inferences or decisions based on an explicit “if-then” rule system. Such systems rely on extracting a high degree of knowledge about a limited category to virtually render all possible solutions to a given problem. These solutions are then written as a series of instructions to be sequentially followed by a machine.

Machine learning systems, unlike the knowledge-based systems, provide machines with the ability to learn through data input without being explicitly programmed with rules. For example, as just discussed, conventional knowledge-based programming relies on manually writing algorithms (i.e., rules) and programming instructions to sequentially execute the algorithms. Machine learning systems, on the other hand, avoid following strict sequential programming instructions by making data-driven decisions to construct their own rules. The nature of machine learning is the iterative process of using rules, and creating new ones, to identify unknown relationships to better generalize and handle non-linear problems with incomplete input data sets. A detailed explanation of one such machine learning technique is disclosed in the article: Michalski, R. S., Stepp, R. E. “Learning from Observation: Conceptual Clustering,” Chapter 11 of Machine Learning: An Artificial Intelligence Approach, eds. R. S. Michalski, J. G. Carbonell and T. M. Mitchell, San Mateo: Morgan Kaufmann, 1983. Embodiments of the present disclosure implement a prediction model which uses machine learning.

According to some aspects of the present disclosure, the smart closet device 102 may include a computing unit 104 and a memory 106. The computing unit 104 may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, graphical processing units, state machines, logic circuitries, and/or any devices that manipulate signals based on operational instructions. Among other capabilities, the computing unit 104 may be configured to fetch and execute computer-readable instructions stored in the memory 106. In an aspect of the present disclosure, the memory 106 may include any computer-readable medium known in the art including, for example, volatile memory, such as static random access memory (SRAM) and dynamic random access memory (DRAM) and/or nonvolatile memory, such as read only memory (ROM), erasable programmable ROM, flash memories, hard disks, optical disks, and magnetic tapes. The memory 106 may be capable of storing data and allowing any storage location to be directly accessed by the computing unit 104. The smart closet device 102 also includes a display door 108 and a user interface 110. In an example, the display door 108 is positioned on a front face of the smart closet device 102. The display door 108 is configured to open and close to provide access to an enclosed space within the smart closet device 102.

In an example, each image sensor 112 may be a red green blue-depth (RGB-D) camera. An RGB-D camera captures color images (or RGB images) along with per-pixel depth information. Known examples of the RGB-D camera includes a Microsoft® Kinect™ and Asus® Xtion™. In some aspects of the present disclosure, the image sensors 112 may be any imaging device such as a color camera.

In some aspects of the present disclosure, the image sensors 112 may include at least a first image sensor and a second image sensor. The first image sensor may be positioned in the enclosed space within the smart closet device 102 and configured to move across a horizontal axis and a vertical axis of the smart closet device 102. The second image sensor may be positioned on the front face of the smart closet device 102. According to aspects of the present disclosure, the first image sensor may capture a plurality of images of each outfit that is hung on the outfit hanging column. According to some aspects of the present disclosure, the first image sensor may provide the plurality of images of each outfit to the computing unit 104 for generation of a three-dimensional (3D) model of each outfit based on the captured plurality of images. The computing unit 104 may generate the 3D model of each outfit based on the captured plurality of images. In an example, a 3D model of an outfit may represent outfit data including outfit length, shoulder width, sleeve length, chest circumference, waist circumference, and other such information.

Additionally, lighting devices (not shown in drawings) may be installed within the enclosure 304 of the smart closet device 102. Lighting devices may be LED bulbs, incandescent bulbs, compact fluorescent light bulbs (CFL) or a combination of these, although any other type of lighting device may also be included.

Lighting devices are electrically coupled to image sensors 112 which is coupled to one or more batteries and/or to one or more power supply sources. The power supply is preferably four AA batteries, but an optional AC adapter is accommodated. Further, the lighting device is activated by image sensors 112. The lighting device allows for three modes: off, always on, and auto-on-off. In the auto-on-off mode, the lighting device lights when the image sensors 112 detects motion, and unless the image sensors 112 detects that the ambient light is above a certain level at which the lighting device is not needed. Upon detecting motion, the lighting device will light and stay lit for a predetermined time period, e.g. 90 seconds, and then automatically turn off. In an embodiment, lighting device may be turned on always and in an embodiment the lighting device may be turn off upon not detecting a motion for more than a predetermined time period. In an embodiment, the lighting device may turn on for a predetermined time period when display door 108 is opened.

Further, incandescent bulbs may be of 40 or 60 Watts and would provide 290 or 840 Lumens of light, however any other specifications of Wattage may also be included. CFL bulbs may be of 9 or 13 Watts and would provide 550 or 810 Lumens of light, however any other specifications of Wattage may also be included. LED bulbs may be of 6 or 9.5 Watts and would provide 450 or 800 Lumens of light, however any other specifications of Wattage may also be included.

According to some aspects of the present disclosure, the second image sensor may capture a plurality of images of a user(s) when the user(s) is in a vicinity of the second image sensor. A user may be said to be in a vicinity of the second image sensor if the user is in a field of view of the second image sensor. In an example, the field of view may be defined to be about 10 meters in the field of view of the second image sensor. In an example, the second image sensor starts capturing the plurality of images of the user when the user is in the vicinity of the second image sensor for more than a threshold period of time. For example, the second image sensor may start capturing the plurality of images of the user when the user moves into the vicinity and stays for more than 5 seconds.

According to some aspects of the present disclosure, the second image sensor may provide the plurality of images of the user to the computing unit 104 for further processing. The computing unit 104 may be configured to determine a body size of the user based on the plurality of images of the user captured by the second image sensor. The body size of the user is also referred to as body profile of the user. In a non-limiting example, the body size of the user may include height, chest circumference, waist circumference, hip circumference, arm width, arm length, thigh length, thigh circumference, head circumference, and other such information related to body parts of the user. In some aspects of the present disclosure, the body size or body measurements of the user may be pre-stored in the memory 106. For example, in situations where the user is a repeat customer or a regular customer, the body size of the user may have been previously determined and stored in the memory 106 for later use by the computing unit 104. Further, the memory 106 may optionally store information pertaining to the user such as personal details such as name, contact details, purchase history, and the like. The information pertaining to the user including the body size may hereinafter be referred to as user data.

Further, US Published Patent Application No. 2015/0154691 A1 to Curry et al. discloses various methods of generating body profile for users, which in incorporated by computing unit 104 to determine a body size of the user based on the plurality of images of the user captured by the second image sensor.

Images sensors 112 include image sensor 202 and image sensor 302. As shown in FIG. 3, the enclosure 304 of the smart closet device 102 includes a horizontal rail 308 and a vertical rail 310 for the movement of the first image sensor 306. In some aspects of the present disclosure, the enclosure 304 of the smart closet device 102 may include rails located on a top surface of the enclosure 304 extending from a front end to a back end of the enclosure 304 for the movement of the first image sensor 306 along a depth of the enclosure 304. The first image sensor 306 is configured to capture images of the outfits hung on the outfit hanging column 302 in the enclosure 304. The first image sensor 306 moves across a horizontal axis along the horizontal rail 308 and a vertical axis along the vertical rail 310 of the smart closet device 102.

According to an aspect of the present disclosure, for training the smart closet device 102 for a plurality of outfits, the plurality of outfits is placed inside the smart closet device 102. In an example, at a time one outfit may be placed inside the smart closet device 102. In another example, multiple outfits may be placed inside the smart closet device 102 at a time. Examples of an outfit include, but are not limited to, a shirt, a dress, a trouser, and a jacket. The present disclosure henceforth has been explained with reference to one outfit (interchangeably referred to as a first outfit) for the sake of brevity.

Whenever the smart closet device 102 is to be trained for an outfit, an operator of the smart closet device 102 may place the outfit inside the smart closet device 102. In one example, the operator may be an employee or a vendor of a retail store where the smart closet device 102 is deployed. In another example, if the smart closet device 102 is used for a home closet, then the operator may be an end-customer/consumer. In some aspects of the present disclosure, in order to place the outfit inside the smart closet device 102, the operator opens or unlocks the display door 108 of the smart closet device 102 and hangs the outfit on the outfit hanging column 302 of the smart closet device 102, and then closes or locks the display door 108.

According to some aspects of the present disclosure, the operator may open the display door 108 of the smart closet device 102 by one or more of: making a hand gesture, providing a voice command, interacting with the display door 108, and interacting with the control panel 116 of the smart closet device 102. In an example, the operator may wave his or her hand in front of the smart closet device 102 to open the display door 108 of the smart closet device 102. In some examples, the operator may make any kind of hand movement in front of the smart closet device 102 including thumbs up, hand sweep, pointing fist, or any other movement that operator can make with his or her hand. According to aspects of the present disclosure, the second image sensor 202 of the smart closet device 102 may track and recognize the hand gesture of the operator that the operator makes in front of the smart closet device 102. In response, the control panel 116 may trigger actuators to open the display door 108. As may be understood, the smart closet device 102 may be pre-trained for recognizing different hand gestures. In an example, the smart closet device 102 may be pre-trained based on conventional or proprietary methods and techniques.

In some aspects of the present disclosure, the operator may provide a voice command to the smart closet device 102 to open the display door 108. The voice command may be detected by the microphone 118 of the smart closet device 102. The voice command may be one of pre-recorded voice commands. Examples of pre-recorded voice commands may include “open”, “open the door”, “open the closet”, “unlock”, “unlock the door”, and “unlock the closet”, and other such voice commands. In some aspects of the present disclosure, the pre-recorded voice commands may be stored in the memory 106 of the smart closet device 102. In an example, the computing unit 104 may compare the voice command with pre-recorded voice commands to determine if the voice command is one of the pre-recorded voice commands. In response to the determination, the display door 108 gets opened.

According to some aspects of the present disclosure, the operator may interact with the control panel 116 of the smart closet device 102 to open the display door 108. In an example, the operator may press the “door opening” button on the control panel 116 to open the display door 108. In some examples, the operator may input authentication details using a keypad on the control panel 116. For example, the operator may input a password or a passcode to unlock the display door 108. Also, as described above, the display door 108 may be a touch screen. In an example, the operator may tap on the display door 108 to unlock it. In some examples, the operator may manually open the door. Other ways of opening or unlocking the display door 108 are possible and whilst not explicitly discussed, are contemplated herein.

Once the display door 108 gets opened, the operator may hang the outfit on the outfit hanging column 302. The hanging column 302 may be extendable such that it travels a distance of 0.1-0.8 times the height of the closet device 102. A retractable hanging column 302 permits better imaging of individual garments as they are scanned by image sensors 112. Preferably the hanging column 302 is mounted to a top horizontal surface in the interior of the enclosure 304 of the closet device 102. A ratcheting or worm drive-type motor [not shown in drawings] permits extension downwards of the column towards the bottom surface of the interior of the enclosure 304 of the closet device 102 or a rise towards the top of the interior of the enclosure 304 of the closet device 102.

According to some aspects of the present disclosure, the computing unit 104 may identify the outfit category associated with the generated 3D model of the outfit based on the information included in the barcode. The information that is included in the barcode of the outfit may be hereinafter referred to as outfit data.

Thereafter, the computing unit 104 may update the outfit database 114 by storing the generated 3D model of the outfit along with an identifier associated with the identified outfit category. In an example, the identifier associated with the identified outfit category may be pre-defined. In some aspects of the present disclosure, the outfit data may also be stored in the outfit database 114. In a similar manner as described above, outfit data, outfit categories, and 3D models corresponding to remaining outfits (for example, a second outfit, a third outfit, and so on) are generated and stored in the outfit database 114 for future use. Accordingly, the smart closet device 102 is trained for the plurality of outfits.

Although it has been described that the smart closet device 102 generates the 3D models of the plurality of outfits, however, according to an aspect of the present disclosure, the 3D models of the plurality of outfits may be extracted by an external computing device and stored in an external memory. The smart closet device 102 may obtain the 3D models of the plurality of outfits from the external memory for training the smart closet device 102.

According to an aspect of the present disclosure, for selection and trying on the outfits by a user in real-time, the second image sensor 202 of the smart closet device 102 may detect a presence of the user whenever the user is in a vicinity of the second image sensor 202. In some aspects of the present disclosure, the second image sensor 202 of the smart closet device 102 is always kept ON. Whenever the user appears in front of the second image sensor 202 or the user is in the vicinity of the second image sensor 202 for more than a threshold period of time, the second image sensor 202 may detect the presence of the user. In an example, if the user is in the vicinity of the second image sensor 202 for more than 5 seconds, then the second image sensor 202 may detect the presence of the user.

In response to the detection of the user in the vicinity of the second image sensor 202, the computing unit 104 may retrieve the 3D models corresponding to the plurality of outfits from the outfit database 114. In an example, the retrieved 3D models corresponding to the plurality of outfits may include the generated 3D model of the first outfit. Thereafter, the computing unit 104 may generate the user interface 110 on the display door 108 to display the retrieved 3D models corresponding to the plurality of outfits. In some aspects of the present disclosure, the computing unit 104 may receive a selection from the user of the generated 3D model of the outfit from the displayed 3D models corresponding to the plurality of outfits. In an example, the user can select the generated 3D model of the first outfit through hand gestures, voice commands, and/or interaction with the control panel 116 or the display door 108. As described earlier, the display door 108 may be a touch screen. In an example, the user may swipe through the 3D models corresponding to the plurality of outfits and tap on the generated 3D model of the first outfit to make the selection. In another example, the user may make hand gestures to view the 3D models corresponding to the plurality of outfits and select or choose the 3D model of the first outfit. In yet another example, the user may interact with the control panel 116. In yet another example, the user may scan a barcode of the desired outfit using the scanner 120. Other ways of selecting the 3D model of the first outfit (or any other desired outfit) for trying on are possible and whilst not explicitly discussed, are contemplated herein. In an example, the 3D models corresponding to the plurality of outfits may be arranged on the user interface 110 based on outfit categories including a shirt category, a dress category, a trouser category, or a jacket category.

Upon receiving the selection of the generated 3D model of the first outfit, the second image sensor 202 may capture a plurality of images of the user. According to some aspects of the present disclosure, the second image sensor 202 may provide the plurality of images of the user to the computing unit 104 for determination of the body size. The computing unit 104 may then determine the body size of the user based on the plurality of images of the user. In a non-limiting example, the body size of the user may include height, chest circumference, waist circumference, hip circumference, arm width, arm length, thigh length, thigh circumference, head circumference, and other such information related to body parts of the user.

In some aspects of the present disclosure, the smart closet device 102 may be pre-trained for the user. For example, in situations where the smart closet device 102 is deployed for home usage, the second image sensor 202 may use biometrics-based detection such as fingerprint, facial recognition, and the like to identify the user. Upon detecting the user, the computing unit 104 may retrieve the user data (including the body size) from the memory 106 without having to perform determination of the body size of the user based on the plurality of images of the user.

Thereafter, the computing unit 104 may generate an image of the user corresponding to the determined body size of the user on the user interface 110 and overlay the generated 3D model of the first outfit over the generated image of the user on the user interface 110. In an example, the 3D virtual image of the first outfit is displayed on the top of the user's body on the user interface 110. Thus, the user interface 110 provides a visual representation of the outfit on the user without the user actually wearing the outfit. Accordingly, the user can make a purchase decision. In some aspects of the present disclosure, information about the outfit such as size, color, type, description, price, etc., is also displayed on the user interface 110 to assist the user in making the purchase decision. According to an aspect of the present disclosure, the body size (or the body measurement) of the user is also displayed on the user interface 110 for future reference of the user. In a similar manner as described above, the user can select various outfits from amongst the plurality of outfits for trying on and the user can see virtual outfit fitting on his or her image generated corresponding to the determined body size of the user. In an example, the user can keep swiping through and tapping the outfits until the user finds one or more desired outfits.

According to some aspects of the present disclosure, the computing unit 104 may retrieve the 3D models corresponding to the plurality of outfits from the outfit database 114, in response to receiving an input from the user. In an aspect, the user may provide the input to the smart closet device 102 in form of one or more of a hand gesture, a voice command, and an interaction with the control panel 116. In an example, the user may access the smart closet device 102 using a membership card provided by a retail store in which the smart closet device 102 is deployed. For example, the user may swipe the membership card using the access control card reader on the control panel 116. The membership card may store information about the user including the body size of the user. Accordingly, when the user accesses the smart closet device 102 using the membership card, the smart closet device 102 (or the computing unit 104) recognizes the user and retrieves the body size of the user from the membership card. The computing unit 104 may then retrieve the 3D models corresponding to the plurality of outfits from the outfit database 114. In an example, the retrieved 3D models corresponding to the plurality of outfits includes the generated 3D model of the first outfit. The computing unit 104 may then display the 3D models corresponding to the plurality of outfits on the display door 108 (for example, on the user interface 110 generated on the display door 108). The computing unit 104 may then retrieve the generated 3D model of the first outfit, in response to receiving an input from the user and display the generated 3D model of the first outfit on the display door 108 or the user interface 110. In some aspects of the present disclosure, the computing unit 104 may generate an image of the user corresponding to the body size of the user retrieved from the membership card of the user. The computing unit 104 may display the image of the user on the user interface 110. Further, the computing unit 104 may then overlay the generated 3D model of the first outfit over the generated image of the user on the user interface 110.

Accordingly, the smart closet device 102 of the present disclosure facilitates the process of selecting and trying on outfits virtually (for example, the first image sensor 306 and the second image sensor 202) and augmented reality that will help embody outfits on the user body and assist the user in making purchase decision. This not only eliminates the need for users to physically wear the chosen/selected outfits, but also helps the users to make purchase decisions a lot faster and enhance their shopping experience. Thus, the smart closet device 102 allows the users to freely browse, select, and try-on their chosen outfits at their own convenience.
